Example to demonstrate too much boilerplate code while in Backbone.

boilerplate-collection-view.js

var AnyCollectionView = Backbone.View.extend({

    initialize: function() {
        this.collection.on( 'add', this.appendItem, this );
    },

    render: function() {
        this.$el.empty();
        this.collection.each( this.appendItem, this );
        return this;
    },

    appendItem: function( model ) {
        this.$el.append( new AnyModelView({
            model: model
        }).render().$el );
    }

});
